answer:I understand these symptoms very well. While it’s been a long time since I went days with little or not sleep, I remember it well. Everything was heightened. Though I was weary, I couldn’t sleep. I understand the fear of it as well. It may or may not be true, but for me the fear of sleep after so many days without it was due to a wish to control or an aversion to vulnerability. When we’re asleep we’re the most vulnerable. As I mentioned, everything is heightened when I lack sleep: anxiety, phobias, and aches. It’s awful. I wish you the best of luck. Feel free to send me a private message, if you want.
